How Installing Energy-Efficient Windows in Castle Pines Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to take the plunge and make the switch:

  • Save on energy bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll require less energy to heat or cool your house.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Castle Pines

Each window installer offers various services and has varying prices depending on several factors.

How Much Do New Windows Cost?

On average, homeowners in Castle Pines can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. These estimates vary depending on the specifics of your installation, including size, type, material, number of windows, the location of your home and more.

Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

When considering window replacements, there are typically two types that your installer will offer: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

If you're still trying to decide which kind of installation to get, you can ask your provider and get their advice. The choice mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Castle Pines

In our hunt to make your home improvements easier and more eco-friendly in Castle Pines, the EcoWatch Reviews team evaluated many companies before landing on these. We have reviewed the top window installation companies in Castle Pines primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you choose. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, professionalism, cost, quality of parts, quality of installation and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Castle Pines' climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Castle Pines window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Castle Pines, CO Window Replacement FAQs

What is the average cost to install new windows?

The national average cost to replace one window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is usually dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What kind of window is the most energy-efficient?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.

What do window installers do?

Window installation professionals will do the entire process — from replacing old windows with brand new ones to cleaning up after the windows have been put in place. In addition, some companies offer window manufacturing, customization and repairs.

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, the weather should be dry, as rain can make the installation harder.

Should I replace my windows all at once?

If you want to get more efficient windows and save money on your energy bills, replacing all of the windows together is the only way to gain that benefit. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.
